Congruency Basics

Are congruent shapes compatible? Congruent shapes are identical to one another, and throughout the assessment, young mathematicians identify given shapes as congruent.

Some of these may look congruent, but examine them closely. There are three sets of shapes here for scholars to analyze as they circle all the congruent figures. For each set, there are three congruent shapes which are oriented in...

Encourage your scholars to play with math using this shapes partner game, where players toss a number cube (possibly a die) to determine which geometric shape to draw. The students toss the cube a second time to determine whether they...

In this geometry worksheet, students select the shape that is congruent to the one given. There are four multiple choice questions for students to complete.

In this shape recognition instructional activity, students learn to move a shape in different ways by sliding, flipping, or turning it. Students trace a triangle on paper, cut it out, and complete the directions for moving and drawing...

There is more to congruency than just looking similar. Learn the difference and calculate the matching angles and sides to prove the congruence between figures. Lesson has step-by-step slides and follows with an assessment. 

Fourth graders use tangram sets to investigate the congruence of shapes. They use congruent shapes to demonstrate the properties of slides, flips, and turns. They complete a math journal entry that describes and illustrates each concept.

This QuickTime movie provides an opportunity to learn about the basic geometric term congruency. As you watch and listen to the teacher and student interact it helps clarify the thinking behind applying this concept.

Students examine geometric quilt patterns to identify how math may have been used to help slaves escape to freedom. They slide, flip and turn geometric shapes to create a map quilt.
